Target Hackers Accessed Card Data Through a Vendor

The retailer says the thieves stole credentials from a vendor that allowed them to pinch 40 million credit card numbers

Target said Wednesday the hackers that broke into its system and stole millions of customer credit numbers got access to the data by first stealing credentials from a vendor.

A Target spokesperson said the thieves gained access to 40 million credit card numbers and the personal information of 70 million more people by lifting vendor credentials that gave them access to Target systems.

Target says it has taken special precautions since the breach became public on December 15 and that is working with the Secret Service and the Justice Department to resolve the situation.
